In industrial production, due to the strong hygroscopicity of pet raw materials, it is necessary to use a dehumidifying dryer to dehumidify and dry them to ensure that the moisture content of the raw materials is within the standard range and ensure the final molding effect of plastic products. At present, the most important drying equipment in the plastics industry is the dehumidification dryer. How can the dehumidification dryer ensure the physical properties of plastic products?
1. It is equipped with one-time conveying (drying) and two-time conveying (forming), and can be conveyed multiple times as required.
2. Adopt quantitative discharge device to transport raw materials to prevent the material in the material pipe from absorbing moisture.
3. It has a microcomputer P.I.D control system and sound and light alarm device to comprehensively monitor the working conditions of the equipment.
4. With system overload, system overvoltage, fan current protection, material full protection, material shortage alarm, over temperature alarm, poor heating alarm, and cooling delay functions to ensure safe and effective work.
5. Adopt dry air with low dew point, -40 dew point or lower dew point temperature to ensure that the material can be fully dried.
6. Adopt a fully insulated drying hopper to prevent heat loss and ensure uniform temperature.
7. Adopt an integrated closed body design to avoid re-moisture of dried raw materials due to contact with outside air, and achieve a good drying effect.
The dehumidification dryer adopts reasonable design and advanced technical processing to ensure that the raw materials can maintain good physical properties during the dehumidification and drying process to achieve high-quality product molding quality.
